Would like opinions on which brand of leaded water soluble solder has the longest print life. we're currently using Alpha WS-809. Each board goes through the printer every 15 minutes or so, and we wind up re-printing most boards as the solder isn't

0.5 if you use electroformed stencil or > 0.8 if you use laser cut. 2. Always use fresh paste 3. Uses the right printer parameters for your paste(for example Alpha likes fast release of the stencil from the board - in DEK this is called separation s

We have not tried VectorGuard, so I cannot comment on that specific solution. However we have been using a Tecan Genesis system for several years and are very pleased with it. Unlike the DEK solution, the tensioning is entirely mechanical so there is

with 0.5mm pitch I wouldn't go too fast. Check your separation speed as well as your print area(may be you can drive your squeegees 1-2 inches less). Some pastes like Alpha like very fast separation. so you can win another 2-3 seconds from there.What

The recommended wash concentration for stencil cleaning with VIGON SC200 is 25% and this should be confirmed using the ZESTRON BA-20 bath analysis kit. Additional cleaning recommendations are: Wash temperature should be approximately 25 degrees C. /

I agree with you. IPC Committee 5-24b Solder Paste Task Group is responsible for maintaining J-STD-005, Requirements for Solder Pastes. They generate "standards, test methods, and a handbook that reflects current practices in all aspects of electro

Thanks. Yes, we have attempted to use standard ROHS profiles in the past and turned our THT connectors into 'chucky dolls' after the PCBA left the oven. We then realized that we need the high temp nylon connectors to allow for the use inside the SMT
